TEST COOLING CIRCUIT
The cooling circuit is designed for long
durability, and is based only on a few
components. Any testing of the circuit should
be conducted, only if, a relevant problem
has arisen. Open the unit’s outside cover, by
removing the two screws in the lower part.
Locate the service valve, connect a pressure
gauge, and check that the pressure is aligned
with the present temperature. Due to critical
refrigerant changes, low volume refrigeration
hoses with low loss fittings should be used
when accessing the refrigeration system. Care
should be taken to minimize any amount of
lost refrigerant.
